Abstract

SE DESCUBRE UN CATETER (101) EPIDURAL DE UN DIAMETRO EXTREMADAMENTE PEQUEÑO, QUE ES FLEXIBLE Y NO SE ENROLLA AL FLEXIONARSE. EL CATETER (101) INCLUYE UN ESTUCHE TUBULAR O TUBO (104) QUE TIENE DENTRO UN CANAL PARA EL SUMINISTRO DE FLUIDOS AL TEJIDO BIOLOGICO. EN EL CANAL HAY UN ROLLO (105) QUE ESTA ADAPTADO EN EXPANSION PARA FORMAR UNA ESTRUCTURA DE PARED COMPUESTA QUE ES EXTREMADAMENTE FLEXIBLE Y NO SE ENROLLA. ESTA ESTRUCTURA DE PARED SE UTILIZA PARA FORMAR UN CATETER QUE TIENE UN DIAMETRO EXTERIOR PEQUEÑISIMO (106) QUE OSCILA ENTRE 0.010" A 0.032" PARA SUMINISTRAR NIVELES ACEPTABLES DE FLUIDO. EL ROLLO (105) TIENE UNA CANTIDAD DE VUELTAS SEPARADAS (110) QUE VAN DE UN EXTREMO AL OTRO DE ESTE. CERCA DEL EXTREMO FINAL DEL ROLLO (105), HAY UN NUMERO DE VUELTAS O BUCLES, SUELTOS JUNTOS (111) QUE DAN MAS FLEXIBILIDAD A ESTE EXTREMO DEL CATETER (101). EL ESTUCHE TUBULAR (104) DEL CATETER (101) TIENE UN MATERIAL DE GRAN TENSION O RESISTENCIA A LA FLEXION QUE NO SE ROMPE NI RASGA CUANDO EL CATETER(101) SE DOBLA O FLEXIONA. MANTENIENDO LA PROPORCION DEL DIAMETRO EXTERIOR (107) DEL ROLLO DE CABLE (105) CON EL DIAMETRO SECCIONAL (113) DE LAS VUELTAS INDIVIDUALES EN UN LIMITE DE 4 A 10 PREVIENE AL ESTUCHE TUBULAR (104) DE ROMPERSE O ENREDARSE CUANDO EL CATETER (101) ES DOBLADO O FLEXIONADO.AN EPIDURAL CATHETER (101) OF AN EXTREMELY SMALL DIAMETER IS DISCOVERED, WHICH IS FLEXIBLE AND DOES NOT ROLL WHEN FLEXING. THE CATHETER (101) INCLUDES A TUBULAR CASE OR TUBE (104) THAT HAS INSIDE A CHANNEL FOR THE SUPPLY OF FLUIDS TO THE BIOLOGICAL TISSUE. THERE IS A ROLL (105) IN THE CHANNEL THAT IS ADAPTED IN EXPANSION TO FORM A COMPOSITE WALL STRUCTURE THAT IS EXTREMELY FLEXIBLE AND DOES NOT COIL. THIS WALL STRUCTURE IS USED TO FORM A CATHETER THAT HAS A SMALL OUTER DIAMETER (106) THAT RANKS BETWEEN 0.010 "TO 0.032" TO SUPPLY ACCEPTABLE LEVELS OF FLUID. THE ROLL (105) HAS A QUANTITY OF SEPARATE TURNS (110) GOING FROM ONE END TO THE OTHER OF EAST. NEAR THE END OF THE ROLL (105), THERE IS A NUMBER OF TURNS OR LOOPES, LOOSE TOGETHER (111) THAT GIVE MORE FLEXIBILITY TO THIS END OF THE CATHETER (101). THE TUBULAR CASE (104) OF THE CATHETER (101) HAS A MATERIAL OF HIGH VOLTAGE OR RESISTANCE TO FLEXION THAT DOES NOT BREAK OR RIP WHEN THE CATHETER (101) FOLDS OR FLEXS. MAINTAINING THE PROPORTION OF THE OUTER DIAMETER (107) OF THE CABLE ROLL (105) WITH THE SECTIONAL DIAMETER (113) OF THE INDIVIDUAL TURNS IN A LIMIT OF 4 TO 10 PREVENTS THE TUBULAR CASE (104) FROM BREAKING OR ENTRAWING WHEN THE CATHETER (101 ) IS BENT OR FLEXED.
